Theory Quotes
-
The big picture, I think, is that common ancestry is evidentially prior to natural selection in Darwin's theory and in contemporary evolutionary biology as well.
Elliott Sober -
It is a test of true theories not only to account for but to predict phenomena.
William Whewell
-
Qualities I sought in a scientific theory were naturalness, inner perfection and logical simplicity from an aesthetic approach.
Albert Einstein -
It has become inordinately difficult even to begin to think about constructing a naturalistic theory of the evolution of that first reproducing organism.
Antony Flew -
I'm not a yeller. My theory is that no one goes out there trying to screw up.
Amy Ruley -
Evolution is an organizing principle and when we call it a theory, we mean it's a theory, we don't mean that it's a belief that someone holds.
Alan I. Leshner -
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
Albert Einstein -
There's not a single shred of evidence for the multiverse. If, in order to explain this universe, you need a theory that invents an infinite number of parallel universes - that's not a very good theory.
Adam Frank
-
General systems theory is the scientific exploration of "wholes" and "wholeness" which, not so long ago, were considered metaphysical notions transcending the boundaries of science. Hierarchic structure, stability, teleology, differentiation, approach to and maintenance of steady states, goal-directedness — these are a few of such general system properties.
Ervin Laszlo -
All such problems can be formulated as mathematical programming problems. Naturally, we can propose many sophisticated algorithms and a theory but the final test of a theory is its capacity to solve the problems which originated it.
George Dantzig -
Healing of the world's woes will not come through this or that social or political theory; not through violent changes in government, but in the still small voice that speaks to the conscience and the heart.
Arthur James Moore -
You feel as if you're not living a full life. Which, of course, is why - it's my theory about why so many people who are heavily into computers are also into extreme sports and S&M. It's because their bodies are crying out for some kind of action.
Brian Eno Roxy Music -
E pur si muove. "Albeit It does move". (That's what Galileo purportedly muttered after torturers forced him to recant his theory that the earth orbits the sun.)
Galileo Galilei -
My theory of composition? Simple: do not release the shutter until everything in the viewfinder feels just right.
Ernst Haas
-
What did being connected to the world get you? It got you sadder. Look, the world is not sane. If you stay connected to an insane world, well, you just go crazy. This is not a complicated theory. It's just simple logic.
Benjamin Alire Saenz -
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
Albert Einstein -
Lack of specificity around stakeholder identity remains a serious obstacle to the further development of stakeholder theory and its adoption in actual practice by business managers. Nowhere is this shortcoming more evident than in stakeholder theory's treatment of the constituency known as 'community.
R. Edward Freeman -
It has seemed to me that the theory (calcul) of probabilities ought to serve as the basis for the study of all the sciences, and particularly of the sciences of observation.
Adolphe Quetelet -
Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.
William Stanley Jevons -
A new theory is guilty until proven innocent, and the pre-existing theory innocent until proven guilty ... Continental drift was guilty until proven innocent.
David M. Raup
-
More philosophically-minded critics regarded Einstein's argument for relativity as little more than a logical bait-and-switch ploy: "The supposition of most expounders of the Special Theory, that Einstein has proved the relativity of simultaneity in general - or that his 'simultaneity' is something more than a logical artefact - must manifestly be given up.
Arthur Oncken Lovejoy -
It's kind of hard to sell 'trickle down,' so the supply-side formula was the only way to get a tax policy that was really 'trickle down.' Supply-side is 'trickle-down' theory.
David Stockman -
In theory, it makes a lot of sense to combine the two operations, especially on the back end. But merging the two actual portal consumer experiences into a unified site will be a nightmare.
Charlene Li -
Partial knowledge is more triumphant than complete knowledge; it takes things to be simpler than they are, and so makes its theory more popular and convincing.
Friedrich Nietzsche
